Research On The Mathematics Situational Teaching Based On Constructivism In Junior Middle School

With the continuous progress of the new curriculum reform in basic education,situational teaching method has gradually become one of the effective ways to promote the reform of teaching methods.The effective implementation of situational teaching is not only conform to the characteristics of physical and psychological development and the law of cognitive development in junior middle school students,but also has achieved remarkable results in promoting the three-dimensional teaching objectives of knowledge and skills,processes and methods,emotional attitudes and values.In the mathematics situation teaching process of junior middle school,teacher can create some situation which can relate to teaching contents to combine system knowledge with things and scenes that students are familiar to.Situational teaching is helpful to cultivate students' exploring consciousness and the ability to find and solve problems.Constructivism emphasizes on the student-centered in the teaching process,teacher should create a good learning environment and focus on students' learning motivation,situational and social interaction,which has an important guiding significance to promote the development of situational teaching.On the basis of expounding the relationship between constructivism and junior middle school mathematics situation teaching,this paper analyzes the existing problems in the implementation of junior middle school mathematics situation teaching by means of questionnaire survey and classroom observation,analyzes and discusses the implementation principle,the implementation prerequisite and the implementation link of the situational teaching in junior high school with constructivism,and then puts forward some specific strategies for optimizing the implementation of junior middle school mathematics situation teaching,finally the lesson plan is designed to guiding teaching practice for testing the results of the implementation.The paper mainly consists of the following six parts:The first part is the introduction.This part mainly introduces the research background and significance from the aspects of new curriculum reform,the law of physical and psychological development of junior middle school students,the characteristics of junior middle school mathematics and constructivism,etc.And the correlated research about home and abroad is summarized.This part also elaborates the research contents and methods.The second part is an overview of constructivism and junior middle school mathematics situational teaching.After summarizing on the basic of constructivism and situational teaching,the internal relations between constructivism and junior middle school mathematics situational teaching are discussed;Next,extracting the innovation of the paper by analyzing and comparing the characteristics of the situational teaching and junior middle school mathematics situational teaching under the guidance of constructivism,and then explores the significance of junior middle school mathematics situational teaching based on constructivism.The third part is the investigation and analysis of present implementation of mathematics situational teaching in junior middle school.This section is mainly to understand the present situation of the junior middle school mathematics situation teaching through questionnaire survey and classroom observation,and then analyses what the teacher should pay attention to in the implementation process of junior middle school mathematics situation teaching.The fourth part is about the junior middle school mathematics situational teaching based on constructivism.Firstly,this part discusses the principles of junior middle school mathematics situational teaching in the course of application,such as the principle of unity between subjectivity and guidance,the principle of unity between intuitive and enlightening,the principle of unity between timeliness and appropriateness,the principle of unity between life and scientificalness;Secondly,elaborating the implementation prerequisite and link of situational teaching.Finally,on the base of the constructivism,the strategies of how to create situations are proposed: to create problemsituation based on life;to create active situation based on cooperation;to create multimedia situation by means of practice;to create history situation through historical material.The fifth part is about teaching design of junior middle school mathematics situational teaching.On the base of situational teaching principles and strategies,this part show a teaching plan to guide how to teaching for testing the feasibility of the implementation.In order to find out weak points,teaching summary and reflection are very necessary.The sixth part is the conclusion and prospect of the paper.
